$\rho =\frac{m}{V} \rightarrow V=\frac{4}{3}\pi r^{3}$

Massa = kontans = 20,25gr

Jari-jari = konstan = 1,23

$\rho =\frac{20,25}{\frac{4}{3}\left ( 2,14 \right )\left ( 1,23 \right )^{3}}=2,59 gr/cm^{3}$

$\bar{\rho _{1}}=\frac{\sum \rho }{n}=\frac{23,35}{5}=4,67 gr/cm^{3}$

$\Delta {\rho _{1}}=\frac{\sum \left | \rho _{1}-\bar{\rho _{1}} \right |}{n}=\frac{0}{4,67}=0 gr/cm^{3}$

$R_{n}= \frac{\Delta \rho _{1}}{\rho _{1}}100^{0}/_{0}= \frac{0}{4,67}100^{0}/_{0}=0^{0}/_{0}$

$\rho _{1}=\left |\rho _{1}+-\Delta \rho _{1} \right |=\left | 4,67+-0 \right |gr/cm^{3}$
